Description

Technical Field

[0001] This invention belongs to the field of solid-state battery technology, and in particular relates to a terminal shaping device for solid-state batteries. Background Technology

[0002] During the assembly and post-processing of solid-state batteries, the terminals are prone to skewing, bending, or uneven end faces due to processing, transportation, and assembly stress. This not only affects the accuracy and consistency of subsequent busbar welding and terminal sealing assembly, but also causes abnormal current transmission paths and excessive contact resistance, which in turn affects the overall internal resistance uniformity and cycle stability of the battery. To ensure the assembly accuracy and conductivity reliability of the terminals, it is necessary to use a special shaping device to straighten, round, and level the end faces of the terminals to ensure that their dimensional and positional tolerances meet the assembly and usage requirements.

[0003] Existing electrode shaping devices mostly adopt integral molding or single-sided, single-point pressure structures. During the shaping process, the force is concentrated on a local area of ​​the electrode, which can easily lead to stress concentration at the root of the connection between the electrode and the cover plate. Long-term or single overload can easily cause micro-cracks at the root, creating potential structural failure hazards. At the same time, integral pressure can transfer the force to the cover plate area, causing the cover plate to warp, dent, and deform, damaging the integrity of the sealing structure between the electrode and the cover plate, causing problems such as sealing failure and reduced air tightness. This seriously affects the safety performance and service life of solid-state batteries, making it difficult to meet the needs of large-scale production of high-reliability solid-state batteries.

[0004] To address this issue, a terminal shaping device for solid-state batteries is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a terminal shaping device for solid-state batteries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a terminal shaping device for solid-state batteries, comprising a mounting frame, wherein a controller is fixedly connected to the side wall of the mounting frame, and further comprising:

[0007] A fixing component is disposed on the inner wall of the mounting bracket for fixing the solid-state battery position;

[0008] A detection component, positioned above the mounting bracket, is used to detect the shape of the fixed battery terminals;

[0009] Two shaping components are disposed on the upper inner wall of the mounting bracket for shaping the terminals of the solid-state battery.

[0010] Two auxiliary components are disposed on the upper sidewall of the mounting bracket to improve the shaping performance of the solid-state battery terminals.

[0011] In the aforementioned electrode shaping device for solid-state batteries, the fixing assembly includes a fixing plate fixedly connected to the inner wall of the mounting frame. A lifting electric push rod is fixedly connected to the lower side wall of the fixing plate. The moving end of the lifting electric push rod passes through the fixing plate and is fixedly connected to a lifting box via a pressure sensor. A limit frame is placed inside the lifting box.

[0012] In the aforementioned electrode shaping device for solid-state batteries, the detection assembly includes a detection plate located above a mounting frame. A lead screw linear module is fixedly connected to the lower side wall of the detection plate. Support columns are fixedly connected to the four corners of the lower side wall of the detection plate. The lower ends of the support columns are fixedly connected to the mounting frame. A moving plate is fixedly connected to the moving end of the lead screw linear module. A detection electric push rod is fixedly connected to the lower side wall of the moving plate. An elastic rod is fixedly connected to the moving end of the detection electric push rod via a pressure sensor. The pressure sensor is electrically connected to a controller. A detection cylinder is fixedly connected to the lower end of the elastic rod. The inner diameter of the detection cylinder is adapted to the size of the electrode of the solid-state battery to be tested.

[0013] In the aforementioned electrode shaping device for solid-state batteries, both shaping components include mounting rings located inside a mounting frame. The mounting rings are fixedly connected to the upper inner wall of the mounting frame via multiple connecting pins. The upper inner wall of the mounting frame has a detection port. Multiple guide cylinders are circumferentially distributed on the side wall of the mounting ring. Guide rods are movably inserted into the guide cylinders, passing through them. One end of the guide rod located inside the mounting ring is fixedly connected to a shaping plate. Two springs are fixedly connected between the shaping plate and the mounting ring. The end of the guide rod away from the shaping plate passes through the mounting ring and is fixedly connected to a ramp block. Four small electric push rods are fixedly connected to the upper inner wall of the mounting frame. The moving ends of two small electric push rods located on the same side pass through the mounting frame and are fixedly connected to the same lifting ring. Multiple push blocks that match the ramp blocks are circumferentially distributed on the inner wall of the lifting ring.

[0014] In the aforementioned electrode shaping device for solid-state batteries, both auxiliary components include air pumps. The two air pumps are symmetrically fixedly connected to the upper side wall of the mounting frame. Two heating boxes are symmetrically fixedly connected to the upper side wall of the mounting frame, and multiple heating wires are connected inside the heating boxes. The air outlet of the air pump is connected to the heating box. An air supply pipe is fixedly connected to the side wall of the heating box away from the air pump. An air supply chamber is opened inside the mounting ring. The lower end of the air supply pipe passes through the mounting frame and the mounting ring and is connected to the air supply chamber. Multiple exhaust chambers are opened below the air supply chamber. The exhaust chambers on the same side are connected to the same telescopic pipe with a single telescopic pipe. The lowermost shaping plate has a hollow structure, and multiple exhaust holes are opened on the inner wall away from the mounting ring.

[0015] In the above-mentioned electrode shaping device for solid-state batteries, the inner walls of multiple shaping plates away from the mounting ring are provided with guide grooves, and a sealing block is fixedly connected to the inner wall of the lowest shaping plate.

[0016] In the above-mentioned electrode shaping device for solid-state batteries, a plurality of annularly distributed bent rods are fixedly connected to the lower side wall of the mounting ring, and the same limiting ring plate is fixedly connected to one end of the plurality of bent rods that are close to each other. The center of the limiting ring plate and the center of the mounting ring are located on the same vertical line.

[0017] In the aforementioned electrode shaping device for solid-state batteries, the outer wall of the detection cylinder is fixedly connected with bristles, which are made of metal.

[0018] Compared with existing technologies, the advantages of a terminal shaping device for solid-state batteries are:

[0019] 1. Through the designed shaping components, when shaping the solid-state battery terminals, the shaping force can be evenly distributed along the circumference of the terminal and gradually applied axially. This avoids the problem of stress concentration at the root of the terminal and micro-cracks caused by traditional concentrated pressure. At the same time, the multi-point flexible bonding shaping structure can significantly reduce the transmission of force to the cover plate, effectively prevent the cover plate from deforming, and ensure the sealing integrity at the connection between the terminal and the cover plate. Furthermore, multi-cell segmented shaping can achieve precise straightening and uniform rounding of the terminal, significantly improving the terminal shape and position accuracy and shaping consistency, reducing the risk of damage to the terminal surface and the overall battery structure during the shaping process, and better meeting the high reliability and high precision production requirements of solid-state batteries.

[0020] 2. By using the set detection components, the condition of the solid-state battery terminals is detected before shaping, and qualified terminals that do not need to be shaped are accurately identified. The shaping process can be skipped to avoid unnecessary mechanical extrusion. This eliminates problems such as stress concentration at the root of the terminal, micro-cracks, deformation of the cover plate, and damage to the sealing structure caused by excessive pressure. At the same time, it reduces ineffective processes and equipment losses, improves overall processing efficiency, ensures the original structural integrity and performance of qualified terminals, and improves battery production yield and product reliability.

[0021] 3. By using auxiliary components, the solid-state battery terminals are slightly heated and assisted in shaping. This can appropriately reduce the hardness of the terminal material and improve its plastic deformation capacity. During the shaping process, the required shaping force can be effectively reduced, alleviating stress concentration at the root of the terminal and reducing the risk of microcrack initiation and propagation. At the same time, the influence of the shaping force on the cover plate and sealing structure can be reduced. After shaping, timely cooling can quickly solidify the terminal, suppress deformation rebound, and ensure the stability of dimensional accuracy and geometric tolerances after shaping. This not only improves the shaping effect and yield rate, but also better protects the integrity of the terminal and the overall battery structure. Attached Figure Description

[0031] The fixing component 3 is set on the inner wall of the mounting frame 1. The fixing component 3 includes a fixing plate 301 fixedly connected to the inner wall of the mounting frame 1. A lifting electric push rod 302 is fixedly connected to the lower side wall of the fixing plate 301.

[0032] The detection component 6 is located above the mounting frame 1. The detection component 6 includes a detection plate 61 located above the mounting frame 1. A lead screw linear module 62 is fixedly connected to the lower side wall of the detection plate 61. Support columns 7 are fixedly connected to the four corners of the lower side wall of the detection plate 61. The lower end of the support columns 7 is fixedly connected to the mounting frame 1. A moving plate 8 is fixedly connected to the moving end of the lead screw linear module 62. A detection electric push rod 9 is fixedly connected to the lower side wall of the moving plate 8. An elastic rod 10 is fixedly connected to the moving end of the detection electric push rod 9 through a pressure sensor 30. The pressure sensor 30 is electrically connected to the controller 2. A detection cylinder 11 is fixedly connected to the lower end of the elastic rod 10. Brush bristles 29 are fixedly connected to the outer wall of the detection cylinder 11. The brush bristles 29 are made of metal. The inner diameter of the detection cylinder 11 is adapted to the size of the solid-state battery terminal to be tested, and is used to detect the shape of the fixed battery terminal.

[0033] Two shaping components 12 are disposed on the upper inner wall of the mounting frame 1. Each shaping component 12 includes a mounting ring 121, which is located inside the mounting frame 1. The mounting ring 121 is fixedly connected to the upper inner wall of the mounting frame 1 by multiple connecting pins. The upper inner wall of the mounting frame 1 has a detection port (for easy insertion of the electrode post). Multiple guide cylinders 122 are distributed in a ring on the side wall of the mounting ring 121. A guide rod 13 is movably inserted into the guide cylinder 122, passing through the guide cylinder 122. A shaping plate 14 is fixedly connected to one end of the guide rod 13 located inside the mounting ring 121. The inner side of the multiple shaping plates 14 away from the mounting ring 121 is... The walls are provided with guide grooves 25. A sealing block 26 is fixedly connected to the inner wall of the bottom shaping plate 14. Two springs are fixedly connected between the shaping plate 14 and the mounting ring 121. The end of the guide rod 13 away from the shaping plate 14 passes through the mounting ring 121 and is fixedly connected to the inclined block 15. Four small electric push rods 16 are fixedly connected to the upper side wall of the mounting frame 1.

The inner wall of the lifting ring 17 is provided with multiple push blocks 18 that match the inclined block 15, which are used for the shaping of the terminal posts of the solid-state battery.

[0034] Two auxiliary components 19 are disposed on the upper side wall of the mounting frame 1. Each auxiliary component 19 includes an air pump 191. The two air pumps 191 are symmetrically and fixedly connected to the upper side wall of the mounting frame 1. Two heating boxes 192 are symmetrically and fixedly connected to the upper side wall of the mounting frame 1, and multiple heating wires are connected inside the heating boxes 192. The air outlet of the air pump 191 is connected to the heating box 192. An air supply pipe 20 is fixedly connected to the side wall of the heating box 192 away from the air pump 191. An air supply chamber 21 is provided inside the ring 121. The lower end of the air supply pipe 20 passes through the mounting bracket 1 and the mounting ring 121 and is connected to the air supply chamber 21. Multiple exhaust chambers 22 are provided below the air supply chamber 21. The exhaust chambers 22 on the same side and the lowermost shaping plate 14 are connected by the same telescopic pipe 23. The lowermost shaping plate 14 has a hollow structure and multiple exhaust holes 24 are provided on the inner wall of the side away from the mounting ring 121 to improve the shaping performance of the solid-state battery terminal.

[0035] Multiple annularly distributed bent rods 27 are fixedly connected to the lower side wall of the mounting ring 121. The ends of the multiple bent rods 27 that are close to each other are fixedly connected to the same limiting ring plate 28. The center of the limiting ring plate 28 and the center of the mounting ring 121 are located on the same vertical line.

[0036] The operating principle of the present invention is explained as follows: The solid-state battery to be tested is placed in the limiting frame 5 of the lifting box 4. The horizontal direction of the solid-state battery is fixed by the lifting box 4 and the limiting frame 5. Then, the operator sends an electrical signal to the controller 2 through an external switch. After receiving the electrical signal, the controller 2 first controls the lifting electric push rod 302 to work. The lifting electric push rod 302 drives the lifting box 4 and the solid-state battery to move upward together through the pressure sensor. During the upward movement, the solid-state battery will drive the two terminals to pass through the two limiting ring plates 28 respectively and move into the mounting ring 121. When the upper cover plate of the solid-state battery contacts the limiting ring plate 28, the solid-state battery will stop moving. The lifting electric push rod 302 will continue to apply pressure to the lifting box 4. The controller 2 detects that the pressure between the cover plate and the limiting ring plate 28 reaches the set threshold (100N) through the pressure sensor between the lifting electric push rod 302 and the lifting box 4. Then the controller 2 will control the lifting electric push rod 302 to stop working.

[0037] Subsequently, controller 2 controls the linear screw module 62 to operate, which drives the detection electric push rod 9, elastic rod 10, and detection cylinder 11 to move directly above the pole post. Then, controller 2 controls the detection electric push rod 9 to operate, causing the detection electric push rod 9 to drive the elastic rod 10 and detection cylinder 11 to move downward to the set position. When the pole post is not deformed, the detection cylinder 11 will move smoothly to the lower set position. When the pole post is deformed, the pole post and the detection cylinder 11 will come into contact with each other. After controller 2 detects the compressive force between the detection cylinder 11 and the pole post through the pressure sensor 30, it indicates that the pole post is deformed and needs to be adjusted. Controller 2 will then control the detection cylinder 11 to separate from the pole post.

[0038] Next, controller 2 controls the heating wire (not shown in the diagram) inside the heating chamber 192, the air pump 191, and four small electric push rods 16 to work simultaneously. The air pump 191 delivers external gas into the heating chamber 192, heats it with the heating wire, and then delivers it to the air delivery chamber 21 through the air delivery pipe 20. Then, it is delivered to the multiple shaping plates 14 at the bottom (the bottom shaping plate 14 is a hollow structure) through the exhaust chamber 22 and the telescopic pipe 23, and then discharged through multiple exhaust holes 24. Under the action of the sealing block 26 and the guide groove 25, the hot airflow blows evenly upward along the circumference of the pole post. At the same time, the small electric push rods 16 drive the lifting ring 17 to move upward, and the lifting ring 17 drives multiple push blocks 18 to move upward together. When the push blocks 18 contact the multiple inclined blocks 15 at the bottom, the gas flows through the push blocks 18 and the inclined blocks 15. With the sliding engagement of block 15, the bottom inclined block 15 will drive the bottom shaping plate 14 to contact the terminal post through the guide rod 13. The bottom multiple shaping plates 14 are closed into a circle, which can squeeze and shape the bottom of the terminal post. Similarly, as the push block 18 moves upward step by step, multiple shaping plates 14 at different heights will squeeze and shape the terminal post, avoiding the problem of stress concentration at the root of the terminal post and micro-cracks caused by traditional centralized pressure. At the same time, the multi-point flexible fitting shaping structure can greatly reduce the transmission of force to the cover plate, effectively prevent the cover plate from deforming, and ensure the sealing integrity at the connection between the terminal post and the cover plate. Moreover, multi-unit segmented shaping can achieve precise straightening and uniform rounding of the terminal post, significantly improve the shape and position accuracy and shaping consistency of the terminal post, and reduce the risk of damage to the surface of the terminal post and the overall structure of the battery during the shaping process.

[0039] Furthermore, after the pole post is shaped, the controller 2 will control the heating wire to stop working while the air pump 191 is in operation, so that the shaped pole post can be cooled and solidified more quickly, suppressing deformation and springback, and ensuring the stability of dimensional accuracy and geometric tolerance after shaping.

[0040] Experimental data table on the effect of temperature on the shaping effect of solid-state battery terminals:

[0041] Heating temperature (°C) Polarity error (μm) Polar column straightness error (μm) Root microcrack rate (%) Cover plate deformation (μm) Cosmetic surgery pass rate (%) Room temperature (25) 42 38 8.5 16 81.5 40 31 27 5.2 12 88.0 60 20 18 2.1 8 95.6 80 12 10 0.8 5 98.7 100 9 7 0.3 3 99.4 120 15 13 1.2 7 96.1 140 28 25 4.6 11 89.3

[0042] Experimental conclusion: The optimal temperature range is 80–100℃, which results in the highest pole shaping accuracy, the least cracks and cover plate deformation, and a pass rate close to 100%.
